Heredity and environment a critical survey of recently published material on twins and foster children

"This book is a critical survey of the methods and findings of nature and nurture research. It appraises recent studies of foster children, including studies of twins reared apart, which attacked the problem of the influence of heredity and environmental factors in intelligence and achievement. The author has analyzed with his characteristic scientific objectivity and clarity of expression the research results already achieved. He has indicated that these studies are in substantial agreement as to the indispensability of both genetic and environmental factors in mental development and has suggested further research necessary to obtain valid conclusions concerning unsolved crucial problems. He also calls attention to the importance in future studies of integrating the points of view and the methods of research from the fields of anthropology, genetics, psychology, and sociology. His analysis, it is hoped, will stimulate research that will take full account of the deficiencies and shortcomings of past studies as well as of their positive contributions to methodology. This book will be helpful not only to those engaged in research on twins and foster children but also to all interested in the role of the genetic and environmental factors in human behavior."
